It depends on your plan: 1 day on Free, 15 days on Pro, 30 days on Studio. After that, both the result and the source file are deleted for good, with no way to recover them. Download what you need before it expires.

Files are processed in the same format as they are uploaded so the result is in the highest quality possible. No algorithm is perfect, but we tune ours to keep the voice natural, intelligible and free of robotic artefacts — and we keep improving it.

Each plan includes a number of audio minutes you can process per month. Spread them over as many files as you like: with 10 minutes you can process 3 files of 3 minutes, or 2 files of 5 minutes. Files round up to the next minute — 1 minute 28 seconds counts as 2 minutes. Minutes renew every month and don't stack.

In the browser: the common audio containers — MP3, WAV, FLAC, M4A, OGG, AAC, AIFF. Through the desktop app: those same formats plus video — MP4, MOV, WEBM — whose audio is extracted locally. On the way out: a lossless audio file, in the same family as the source where possible.

No. KeepVocals does one thing: it removes the music and the background from a recording and gives you back a clean voice file. We don't export drums, bass, instrumentals or a music-only track. If you need a karaoke or a multi-stem split, this isn't the right tool.

No. Whether your file is ten seconds or three hours, the flow is the same. Long files take longer to process, but they're not capped.

Only you. Files are uploaded directly from your browser to our storage and are not shared with third parties. They are deleted according to the retention rules above, or whenever you delete them manually.

Yes, through the desktop app. It extracts the audio track from your MP4, MOV or WEBM right on your machine, sends us the audio only, then reassembles the result with your original video — which is never modified and never leaves your computer. The browser itself only accepts audio files.
